It is said that love is unconditional when love is given freely to some no matter what. It doesn’t have to be earned on the basis of certain conditions.
This kind of love is mostly expressed by parents towards their children, no matter what a child does wrong; a parent will always love his or her child.
On the other hand, conditional love is a type of loved that has to be earned, one has to make conscious effort to earn this love. Many believe this is not the “real” kind of love and unconditional love is the true form of love.
